Very nice song and liked the video as well. Maybe you could try not to sing so exactly in-takt. Meaning, loosen up, sing a little smoother. If you can turn off the drums to record your voice, try that.

I began in 1970 with a 7 piece dance band. I had other bands, but my most successful one was "The four Windows", a 4 piece guitar band. Many concerts, TV shows, Record contract with EMI and a guitar hit in 1982 in Europe with my "Lonely Seagull".
